Simplified synchronous machine rotor type / Simulink

In Simulink library, There are two types of synchronous machines.

One is datailed machine and the other one is simplified synchronous machine.

In detailed synchronous machine block, there is a check list to choose rotor type(salient and round)

However, there is no check list about rotor type in simplified synchronous machine block.

So I want to know about the reason.

I guessed 2 cases.

First is that there is no difference between round and salient type in simplified model

Second one is that simplified model use only round rotor.

I want to get good feedback from you

Thank you
